ELEVATOR FOR LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 509,437, dated November28, 1893.

Application led February A2, 1893. Serial No. 460.674. (No model.)

To a/ZZ whom. t may concern:

Be it known that I, SYLVESTER JENKINS, o Lansdale, county of Montgomery,and State of Pennsylvania, have invented an Improvement inLiquid-Elevators, of `which the following is a specification.

Myinvention relates to elevators for liquids, and consists of certainimprovements which are fully set forth in the following specificationand are shown in the accompanying drawings which form a part thereof.

My invention is particularly designed for lifting ales and other liquorsfrom a cellar or portion of a building Where they may be kept inquantity, as in the'barrels or kegs, to the bar room or place ofdelivery. Some liquors, such as ales, are injured if they are forcedthrough pipes by pressure as it is necessary that they shouldvbe quietlydrawn from the barrel or keg when desired for use. My invention isdesignedto permit these liquors to be drawn from the barrel or keg intoglasses lowered in the elevator, without rendering it necessary for theattendant to leave the bar or place of delivery.

It is also an object of my invention to enable the attendant to socontrol the delivery of the liquor, that one, two, or more glasses maybe filled at a time, as maybe desired, so that no more liquor may bedrawn from the keg or barrel than is actually required'.

It is also an object of my invention to prevent the overliowing of theglasses While being illed, and also to avoid any spilling of the liquordue to the jolting of the elevator carriage while it is being raised andlowered.

I shall now refer to the accompanying drawings for the purpose ofdescribing my improvements.

In the drawings: Figure l is avertical sectional view of my improvedelevator for liquids. Fig. 2 is a similar View on the line x-a: of Fig.l. Fig. 3 is a plan View of the top of the same. Fig. 4. is a horizontalsectional View on the line y-y of Fig. 2. Fig. 5 is a perspective viewofy the elevator carriage. Fig. 6 is a vertical sectional View on theline .e-z of Fig. 4. Fig. 7 is a longitudinal sectional View of thevalve device on an enlarged scale. Fig. 8 is a horizontal sectional Viewon the line o o of Fig. 2 on an enlarged scale. Fig. 9 is a horizontalsectional view on the line w-w of Fig. 7. Fig. 10 isa similar view onthe line u-u of Fig. 7. Fig. 11 is a similar view on the line t-t ofFig. 7; and Fig. l2 is a vertical sectional view on the line o-v of Fig.2.

A is the elevator shaft, which will usually extend from the cellar, orlower floor at which the liquor is discharged, to an upper iioor orpoint of delivery. The upper portion of the shaft may be located in abar or counter to present a neat and attractive appearance; the upperend of the shaft A may be closed by a cover or cap A provided withapertures a for the glasses, thus concealing the elevator carriage, andits mechanism from view.

B is the carriage which consists of a suitable frame B adapted to movefreely up and down in the shaft A. Carried by the top of the carriageframe B are a series of glass seats or cups C which receive the glassesC. I have shown the frame B provided with four of these seats or cups C,and I consider that number preferable, but more or less may be employedas maybe desired. The seats or cups may be received in sockets or holesc2in the frame B.

The carriage B is guided in its vertical movement by a suitable guide.This I have shown composed of vertical rods B2 Within the shaft Aextending through eyes b in the frame B. Suitable lifting mechanism isconnected with the carriage B for the purpose of raising and loweringit.

The particular form of lifting mechanism which I have shown is asfollows:

D is a small shaft journaled in the upper portion of one of the Walls ofthe shaft A, provided on its outer end with a crank d by which it may berotated.

D and D2 are two disks fast upon the inner ends ofk the shaft D, one ofthe disks, as D2 being of smaller diameter than the other. The largerdisk D is connected by a cord or cable c with the carriage B, so thatthe car` riage B will be raised or lowered in the shaft A, when the cordc is Wound up or unwound upon the disk D when the latter is rotated byits shaft D. The smaller disk D2 is connected by a cord or cable c witha lever D3 hinged to a sliding weight E and having a notch d. The weightE is guidedin suitable guides e in the shaft A. The diskD2 may be IOOprovided with a hub d2. The disks D and D2 may be grooved upon theirperipheries as shown to permit the cords c and c respectively to bewound up upon them. The cords c and e are so disposed with reference toone another that the one will be wound up upon its disk while theotheris being unwound, and vice versa. Thus when the cord cis unwound tolower the carriage B in the shaft, the cord c is wound upon the disk D2and the weight E is elevated. The end of the lever D3 to which the cordc' is connected is provided with a finger d2 which projects over andrests upon the periphery of the disk D2 when the cord c is woundthereon.

The object of employing the smaller disk D2 with its connections, is toprevent the jolting of the carrier B and quietly arrest it when it israised or lowered in the shaft, so as to prevent it from stopping with asudden jolt which might upset the glasses. In Figs. l and 2 I have shownthese devices as they will be when the carriage B is lowered. Then thehandle d is turned to raise the carriage B, the cord c is wound upon itsdisk D and the cord c is unwound from the disk D2 allowing the weight Eto descend. As the disk D2 rotates to unwind the cord c the lever D3 atfirst swings outwardly away from the hub d2 and then descends under theaction of the weight E. During this movement the linger d2 of the leverD3 travels over the periphery of the disk D2. When the carriage B isfully elevated it is on a substantial level with the top of the shaft Aimmediately under the cap or cover A', so that the glass supports C, orthe glasses carried by them, extend up through the apertures Ct. Thenthe carriage B is lowered by turning the handle d to unwind the cord c,the cord c is wound upon the disk D2 elevating the weight E and leverD3. Nhen the cord c is wound upon its disk D2 the end of the lever D2reaches the disk, and as the disk continues to rotate, the finger cl2travels over a portion of the periphery of the disk until it reaches theposition shown in Fig. l, when the notch d lits over the hub d2. W iththis construction the movement of the carriage B when it reaches the topor the bottom of the shaft is gradually arrested without a jolt or jar.Ordinarily1 during the rotation of the disks D and D2 the carriage B israised or lowered for any extent of rotation a distance equal to thelength of cord cor c wound or unwound. Vhen, however, the carriage isalmost lowered in the shaft, the end d2 of the lever D3 comes in contactwith the periphery of the disk D2, and as the disks continue to rotate,it travels over the periphery of the disk D2 until it reaches theposition shown in Fig. 1. At the same time the cord c has been whollyunwound from the disk D', and at the time the end of the lever D3reaches the disk D2 the point of connection of said cord c with the diskD' is approximately ninety degrees from the vertical line. As the diskscontinue to rotate this point of connection travels down with the diskinto the vertical line passing through the axis ofthe disks as shown inFig. l so that the distance which the carriage B is lowered by thisdownward movement is only equal to the vertical distance which the pointof connection of the cord c has moved from its position at ninetydegrees to its position on said vertical line, instead of the distanceequal to the length of the cord that would he unwound from approximatelya quadrant of the periphery of the disk. The movementof the carriage Bis consequently diminished at this point for the same amount oi movementof the disks D D2, and as the movement is a gradually retarded one, thecarriage l5 is quietly arrested in its descent, and without a suddenjar. A similar action takes place when the carriage B is raised. .I ustbefore the carriage reaches its highest elevation, the cord c becomesentirely unwound from the disk D2 and its point of connection with thedisk D2 is approximately forty-live degrees from the vertical linepassing through the axis of the disk. Upon the further rotation of thedisk D2 this point of connection travels down with the disk until itreaches said vertical line and similarly brings the carriage to agradual stop. The finger d2 in traveling over the periphery of the diskD2 also acts to some extent as a brake. The weight E acts tocounterbalanee the carriage B. iVhen the end of the lever D3 reaches theposition shown in Fig. l further movementis arrested. The end d2 of thelever D3 at this moment should be slightly to the right ofthe lineextending from the hinge point of lever with the weight through the axisof the disks D', D2, so that the weight shall not act to turn the diskD2 back and thus again raise the carriage B. The carriage B is thusautomatically stopped and held in its lowered position.

F, F, are liquor pipes extending through the lower portion of the shaftA into a tubular sleeve G located centrally within the shaft A. Thepipes F, F, may be connected externally with the barrels or liquorreservoirs through suitable pipes or hose.

I have shown two 'feed pipes F, F, either' of which may be connectedwith a barrel or reservoir by the valve mechanism hereinafter described.It is to be understood, however, that a single feed pipe may be used.

II is a tubular liquid supply pipe or valve section extending throughthe sleeve G and free to turn therein. This tubular supply pipe or valvesection is provided with valve ports or openings 1', r adapted when thepart I-I is turned to open either of the pipes F, F through the sleeveG. The section Il is also provided with outlets 7L above the pipes F, Ffitted with projecting nozzles h.

F is a rod arranged vertically within the shaft A, journaled at itsupper end, as atf, in a suitable bearing and connected at its lower endwith the upper portion of the valve IOO IIO

section l-l. The rod F may be provided with a handle F2 at its upperportion projecting through a slot g in the shaft A. By moving the handleF2 the rod F may be turned and with it the valve section H so as to openeither of the openings r, fr to the pipes F, F. Whenv a single pipe F isemployed, one opening r will suffice.

I is a tubular valve piece closed at one end and open at the other,located within the valve section I-I with its closed end at the top, andmovable longitudinally within the section H.

The valve piece I is provided with a series of valve holes i, t and Asingle hole t' is located at a distance from the open end of` the pieceI, two holes '11', i', are located in a row at a point below ythe holet', and three holes i2, t2, t2 are located in a row at a point below theholes t', 'i'. The holes t and fi', and t2, t2, t2 are located adistance apart corresponding with'the distance between the outlets h ofthe section H. "With this construction any number of outlets hin thetube H may be opened through the valve piece I.

Normally the Valve piece is in its lowest position within the tube H,and the highest hole is below the level of the outlets h. It is apparentthat with the valve piece I in this position the outlets h will all beclosed. If now the valve piece I be moved up sufficiently to bring thesingle hole 'i in line with the outlets h and the tube I-I be turneduntil one of the outlets h is opposite the hole t', a single outlet hwill be opened, and the liquor may liow through the holes fi and h andthe nozzle h. If the rod be lifted higher, so as to bring the row of twoholes @7,17 in line with the outlets h, two of the valves will beopened. By lifting the piece I still higher until the holes 2 are inline with the outlets h, three of the valves may be opened, and if thepiece I be raised so that its end .passes above the outlets h, all willbe opened.

It will be observed that I have shown the holes t', t" and i2 in thevalve piece I arranged to suit the number of outlets h from the tube H.It the number of these outlets h be increased or diminished the numberof valve openings or holes in the piecelwill of course becorrespondingly altered. The valve piece I is thus provided with valveopenings arranged in successive series of increasing number at differentelevations.

The valve piece I is provided with suitable connections for moving itvertically in the section H. The particular devices for this purposeshown in the drawings are as follows:

I is a rod located within the shaft A and connected by a pin j with thevalve piece I through a slotfin the section I-I. The rod I may beconnected with the pin j by a hinge connection j and the outer end ofthe pin may be guided vertically in a suitable guide j?.

J is a lever pivoted as atv lo on the outside of the shaft A andconnected with the upper end of the rod I, so that when the lever J ismoved on its fulcrum the rod I will be raised or lowered.

It is apparent that the amount of movement of the lever J upon itsfulcrum 7c will regulate the extent of vertical movement of the Valvepiece I and consequently the number of the nozzles h that are opened. Asegmental catch bar S may be arranged upon the outside of the shaftprovided with catches to indicate the extent of movement of the lever Jto open one, two, three or more of the outlets h. The lever J may beguided in its movements in a suitable guide S.

The seats or cups C are arranged upon the upper portion of the frame Bof the carriage B. One or more of these seats or cups may be carried bya yielding supporting piece. Ordinarily it is sufficient for one of theseats or cups C to be so carried.

L is the yielding support for one of the cu ps. In the drawings I haveshown this support as a spring fastened at one end asat Z to the top ofthe frameB and adapted to carry the cup or seat C at its other end.

M is a set screw carried by alug ofthe frame B for adjusting the springsupport L, and thus regulating the amount of its movement.

m is a stop or projection carried by the spring support L.

N is a bell or gong carried by the frame B.

O is a hammer adapted to strike the gong N. The hammer O is pivoted asat o to the frame B and is adapted normally to fall by gravity andstrike the gong N.

O2 is a set screw carried by the hammer O and adapted to strike theframe B when the hammer falls, so as to cause the hammer to strike thegong with a spring blow and return out of contact with it.

O is a weighted dog pivoted to the hammer O or adjacent to it, andnormally bearing upon the hammer below its pivot point so as to hold itout of action in an elevated position as shown in Figs. 5 and 6.

P is a projection located within the shaft A near the bottom and adaptedto strike the dog O when the carriage Breaches its lowest position so asto elevate the dog and lift it out of contact with the hammer O.

P is a linger carried by the hammer O and so located that it willnormally strike the stop m when the hammer is released and prevent itstriking the gong \T.

When the support L is in its normal position, fi. e. when it issustaining the weight of the cup C and the empty glass supportedthereby, the stop m will obstruct the finger P and prevent the hammer Ostriking the gong. When, however, the weight sustained by the support Lis increased by the addition of the liquid to the glass which itcarries, the support L is depressed so as to free the finger I andpermit the hammer O to fall. This device is intended to sound an alarmso as to indicate when the glass has been filled. It is desirable thatthe hammer should not be permitted to strike the gong until the properIIO fr teaser quantity of liquor has been received by the glass. Toinsure this action, and to prevent the accidental release of the hammerO before the glass is filled, which might be caused by a slight jar tothe carriage when it is lowered tending to depress the yielding supportsfor an instant, I prefer to employ a second or auxiliarystop m',locatedimmediatelyin front of the stop m and holding the hammer O, sothat, if for any accidental reason the yielding support L is depressedfor an instant and releases the hammer O, the hammer will be arrested bythe stop m and will be held thereby until the support L is positivelydepressed by the increased weight due to the flow of the liquor in theglass supported by it. By this means the action of the alarm at theproper time is insured. My invention, however, so far as this yieldingsupport and the alarm mechanism controlled thereby, are concerned, isnot limited to the use of an auxiliary stop m'. It will be observed thatas soon as the carriage B is raised so that the weighted dog O is liftedfrom the stop I), the dog O will swing back to its normal position andlift the hammer O.

Q is a stop carried by the frame B and extending over the support L toact as a stop to prevent the spring support rising unduly high when itis relieved of the weight of the glass.

R is a pin carried by the lower extension of the tubular valve piece IIand adapted, when the valve piece H is turned in the manner heretoforedescribed to open the opening 9*, to project over a portion of the frameB so that the carriage may not be elevated in the shaft A until thevalve piece H is turned back and the opening r is closed. As the outletnozzles h are turned with the tube H so as to project over the glasseswhen the carriage B is lowered, it is apparent that if through thecarelessness of the operator the carriage B were raised before the tubeH were turned back the glasses would be caught by the projecting nozzles7L and would be upset. The pin R elfectually prevents this, however, andcompels the attendant to turn the tube H back and close the valve beforethe carriage can be elevated. The pin R thus constitutes a lockcontrolled by the valve mechanism to lock the carriage against movementuntil the valves are closed. IVhile it is highly preferable, it is not,however, essential to the invention.

I shall now describe the operation of this apparatus. In its normalcondition when the carriage B is elevated the tube H is turned in such aposition that the openings r are closed and no liquor may flow throughthe pipes F into the tube H. The valve piece I is in such a positionthat its valve apertures are all out of line with the outlets h. Whenthe tube His in this position the projecting nozzles h are so locatedthat they will present no obstruction to the descending carriage B. Theframe B of the carriage extends about the tube II and rod F so that whenthe carriage is lowered in the shaft the glasses C are grouped about thetube H as is indicated in dotted lines in Fig. 11. This particular shapeof the frame B so as to group the glasses about the tube His, of course,not essential tothe invention. The carriage B when elevated isimmediately below the top or cap A and the glasses C are placed in theseats or cups C. The carriage is then lowered by the rotation of thehandle d in the manner heretofore particularly described,and when itreaches the bottom it will be in the position shown in Figs. l and 2with the tops of the glasses C just below the nozzles h. The stop orprojection P elevates the dog O so as to release the hammer O, which is,however, held out of action by the stop m, as has been explained. Thelever J is now moved to operate the valve piece I according to thenumber of glasses which it is desired to fill. If one glass is to befilled it will be moved so as to bring the single opening 't' in linewith the apertures h, or if more glasses are to be filled, it will bemoved proportionately as has been explained. The extent of the movementof the lever J in each case may be indicated upon the catch bar S. Thehandie F2 is now shifted to turn the rod F and tube H so as to open theport r and permit the liquor to flow through the pipe F into the tube H.IVhen two pipes F, F are employed, the lever may be shifted either tothe right or to the left to open the one pipe F or the other as may bedesired. The turning ofthe tube H to open the port r at the same timeturns the nozzles 71. over the glasses C and brings the outlets 7L incoincidence with the valve openings fi, tbc., so that the liquor mayflow from the nozzles h into the glasses. IVhen the alarm mechanism isemployed with a single glass the outlets t', t', t2, dsc., should be solocated that the single opened valve, or when a series of the outletsare opened one of the series, shall be opened to the glass that issupported by the yielding frame L which con trols the alarm mechanism,so that whether one or more glasses are illed the alarm will be operatedand indicating for one glass, will indicate for all. For this purposethe outlet and one of the outlets of each of the succeeding series as t"and t2 should be in the same vertical line and in a position to supplythe glass carried by the yielding support.

While I prefer the details of construction that have been shown I do notlimit my invention to them as it is apparent that they may be variedwithout departing from the invention.
